No bluetooth, wifi, hotspot after drop

Phone works fully including location, 3g & 4g data, cell service, everything except when it comes to wifi, hotspot, & bluetooth. Phone can not be found / connect to see external devices nor can the phone see external devices. All the icons to turn on the wifi, bluetooth, hotspot work as they should from the software side. This happened after I dropped the phone, never been water damaged. Is this most likely a signal wire that came off (there are two that I see in the tear down video), or a broken part of the mother board? I would like to repair the phone in lieu of replacing for many reasons without having to explain in detail why. Replace the phone comments are not helpful. Thank you for your time!
